Nested IF THEN Statements

[cjsanders]

What is the maximum # of Nested IF THEN's you can have with a 16F877 MCU?

Does the Compiler warn you if you exceed this number?

[mister_e]

as i expect you can have as many as you want or program memory is able to contain them.

I don't see any reason why it should have a maximum. BUT maybe i'm wrong.

Sometime SELECT CASE is a good way to reduce IF THEN statements.

I seemed to remember a Maximum of 4 nested.

I have been trying to call up the manual to doublecheck my
answer, but the site doesn't seem to be working.

That's subroutines with a 4 max. IF... THEN's do not use the stack and therefore have no restriction. The compiler will warn you if you run out of program codespace.

Thanks a MILLION!... I knew I remembered something like a max of 4 on something...Since I may never met that max, I just blow it off.
